Warm-Up Phase (IMB-MPI1, IMB-EXT, IMB-NBC, and IMB-RMA)#
Before starting the actual benchmark measurement for IMB-MPI1
,
IMB-EXT
, IMB-NBC
, and IMB-RMA
, the selected benchmark is
executed N_WARMUP
times with a sizeof(assign_type)
message
length.
The N_WARMUP
value is defined in IMB_settings.h
, see
Parameters Controlling Intel(R) MPI
Benchmarks for details. The warm-up
phase eliminates the initialization overhead from the benchmark
measurement.
